Table 5.
The contactless UART of PN511 and a dedicated external host controller are required to
handle the complete Mifare/ISO 14443A/Mifare protocol.
The internal CRC co-processor calculates the CRC value according to the definitions
given in the ISO 14443A part 3 and handles parity generation internally according to the
transfer speed.
